The 2700 and 2900 models have a USB port that can be used with a 3G dongle for connectivity and/or fallback. The FireBrick 2500 does not have a USB port. By using a 3G dongle with 1one or more FTTC/ADSL lines from AAISP you'll be able to fall back to using 3G in the case of the FTTC/ADSL going down - this includes routing of your public IPv4 blocks and IPv6 blocks (IPv6 via a tunnel). -note,Note: 4G dongles may have a problem with routing public IPs to the FireBrick as they act as a NAT device. In these cases using a L2TP tunnel will enable the IPs to be routed.

Many 4G LTE dongles work by acting as an Ethernet device and perform NAT between the mobile network and the interface presented to the FireBrick. These types of dongles should work OK. If your A&A IP blocks are neededneed to be routed to the FireBrick whilst on 4G then using L2TP would be a way to achieve this. We'llWe’ll be expanding this section with more details and information as we test further dongles.

Multiple USB Donglesdongles can used via a USB hub -, however the benefits of bonding multiple 3G are small, as you'llyou’ll typically be contending with yourself and so there will be little or no added bandwidth.
